Geology of MDI

Duane Braun , Ruth Braun

Selected sites on MDI
Description
Explore the geology of MDI from when MDI was part of the Gander terrane attached to another continent, through the development of MDI as a large volcano, to when glaciers sculpted the present landscape. Each session will be a field trip by car caravan to a location on Mount Desert Island to examine the earth material and landform evidence of the geologic evolution of MDI. Before each class the instructors will send a map and instructions for where to meet for each field trip. Car pooling will be encouraged due to limited parking at some sites. Each class will start with a road side introduction, followed by various degrees of clambering over outcrops. Those with more limited mobility can explore more accessible parts of each site, while more mobile folks can choose more difficult scrambles to examine the geologic features.
